Get a Portion of the Table Stored in a dust Object


Making customized table headers and footers requires a data frame be added to the dust object that has the same column dimension as the rest of the table. In order to reduce the inconvenience of counting columns, get_dust_part extracts the data frame portion currently in use. This ensures the column dimension is correct with the current values, and provides an object suitable for editing.


get_dust_part(x, part = c("head", "foot", "interfoot", "body"))



An object of class dust


character(1), naming the part of the table to retrieve. May be one of "head", "foot", "interfoot", or "body".
